Celtic Woman is an all-female musical ensemble conceived and assembled by Sharon Browne and David Downes, a former musical director of the Irish stage show Riverdance.

In 2004, he recruited five Irish female musicians who had not previously performed together: vocalists Chloë Agnew, Órla Fallon, Lisa Kelly and Méav Ní Mhaolchatha, and fiddler Máiréad Nesbitt, and shaped them into the first lineup of the group that he named Celtic Woman. Downes chose a repertoire that would range from traditional Celtic tunes to modern songs.

Cumulatively, albums by Celtic Woman have sold over 6 million records worldwide.
